<h2>Abstract</h2>
This class is a strategy to update displayer atomiquely
<h2>Discussion</h2>
The aim is to each displayer see the same information in right order and
without loose value.
To perform that, it use to diffent queue, one for operation will set the newValue for sensor
and another to update displayer.
To make atomicity, the strategy builds dependencies between operations:
each update operation is dependent of the new value setter operation.
And if it still remain operation in update queue, the next new value setter operation
is dependent of all remain update operation.
